SRF Seminar: High-Temperature Superconductors (HTS) for RF applications

Friday 1 Oct 2021, 15:00 → 16:00 Europe/Zurich

SRF  R&D seminars are seen as a place to discuss subjects and ideas that are interesting, exciting and or novel. The seminars are informal and seen as a place for open discussion, and topics presented can range from first ideas, through work in progress, to presentation of final results.

Naturally, if you have ideas or suggestions for topics (either presented by yourself or by an invited speaker), please do not hesitate to contact the convenor.

15:00 → 15:40 High-Temperature Superconductors (HTS) for RF applications

I will the discuss the use of High-Temperature Superconductors (HTS) for RF applications, in particular in presence of a strong magnetic field.
This study was triggered by the need of finding a suitable replacement for the copper coating of the FCC-hh beam screen, to minimize beam coupling impedance. This work, performed within a consortium of several European laboratories coordinated by CERN, resulted in very promising initial results.
These results showed that HTS could be an effective alternative in several applications, including exotic studies such as axion detectors, a hot-topic in current particle physics. I will present the fundamentals of the physics behind SRF in magnetic fields, some technologies recently developed and the obtained results.

Speaker: Sergio Calatroni (CERN)
